Be it lknown thnt I, LABN HEATH, of Boston, in the county of Suffolk, mid' State of' Mnssncliusetts, have .invented n new and useful improvement in the Art of Detecting Counterfeit Bnnk-'Notes and I do hereby declare that the following is n' full, clear, und exactdescription of the sume, reference being had to the nnnexed Figure 1 is n representation of severnl genuine vignettes used in printing4 notional bonlmiotes ofthe denominations of $10, $20, $50, und $100, und

Figure 2 is a representation of one-hnlf of the engravings printed on the buck of the $10 und $20 national bnnknotes. A

Connterfeited bank-notes are to be detected byn comparison of the genuino and counteriieited notes. As but comparatively a few persons are 'ot all times in possession of iotes of all the various denominations, in

order to ennblejb'em to make the necessary compa-rion it is desirable that they muy be pnt in possession of at.

least n prtion of -nll the genuine notes in circulation. To print all of :my of the notes would be dangerous, as' affording advantages t-o countcrfeiters, enabling them to transfer such impressions. The sume objection would be to the use of -perfect,impressions of' the whole of uny of the `ports comprising the notes. To obviztte v this objection I propose to print upon clear,` white paper, impressions of only apart of the notes of euch denom- `inotioftfrom dupli'cnates of the original flics und plates, first cutting from such dies `or plates n portion thereof',

which muy be done, as shown in iig. 2, by using only one-bult' of theplnte, or, ns shown in tig. 1, by cutting out of the'die or; plnte a' section. The portion printed will thus be perfect and sueient 'for the purposes of comparison, 'but being imperfect, could not` be used by counterfeiters for the purpose-of printing the entire figure, die,;or pleite, as it would be necessary to add the parts thus removed, which would be represented on. the impressionin ink of the sume color astbot used in making the' impression iniig. 1, where o section is removed. By'the use of duplicates of the'genuin-e dies or plates thus mutilated, I am enabled toplnce, cheaply, in the hands ofthe people, all thtLis necessary for looking comparisons with the counterfeits, und at the same time` to avoid `the danger of an improper use being made of such impressions by eounterfeiters.

What Ieluiut as my invention, und desire to secure by Letters Potent, is

The mode of detecting counterfeit bank-notes by menns'ofimpressions made from duplicates of parts of the.gi enuine dies or-plntes mutilated, substantially in the manner set forth.

y In 4testimony whereof Ihavo signed vmy name to this specification in the presence of two subscribing-witnesses.
